Abstract: A method and apparatus is provided for determining an effective thermal mass of a patient. The effective thermal mass is employed to determine a gain factor used in a feedback control system controlling patient temperature. The method begins by inducing hypothermia or hyperthermia in at least a selected portion of the patient with a device having a heat transfer surface. Next, power is transferred between the device and the patient. A change in temperature over time, which arises in the selected portion of the patient, is measured while performing the step of inducing hypothermia or hyperthermia. Finally, an effective thermal mass is calculated based on the measured power and the measured temperature change over time.

Abstract: A micropositioner has a coarse positioner and a fine positioner, with a separate closed loop control circuit for the fine positioner. A disk head being positioned over a disk is attached to the stage of the fine positioner. The fine positioner includes a parallelogram flexure having first and second opposite sides attached respectively to the coarse positioning stage and the fine positioning stage. A piezoelectric translator translates the second side of the flexure relative to the coarse positioning stage. In order to sense displacement of the fine positioning stage relative to the coarse positioning stage, a differential electric field sensor is employed. The sensor includes a pair of side plates both mounted fixedly relative to one of the stages and opposing each other to create an electrical field between them, and a probe plate mounted fixedly relative to the other of the two stages and between the two side plates.
